We look at the division of 21690169 by 220 
We want to figure out the number of times 21690169 can be divided by 220.

On to step 1:
2 divided by 220 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 220

Step 2:
When dividing 21 by 220, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 220

On to step 3:
When dividing 216 by 220, we get 0 with a remainder of 216.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 216, we end up with 216.
Take the next digit (9) from the dividend and append it to 216, then repeat: 2169 / 220

On to step 4:
The number 220 fits into 2169 9 times, leaving a remainder of 189.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 1980 from 2169 to get 189.
Grab the next digit (0) from the dividend, add it to 189, then carry on: 1890 / 220

Moving on to step 5:
1890 divided by 220 is 8 with a remainder of 130.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Subtracting 1760 from 1890 leaves us with 130.
Fetch the next digit (1) from the dividend, attach it to 130 and continue: 1301 / 220

Moving on to step 6:
The number 220 fits into 1301 5 times, leaving a remainder of 201.
The next digit of our result is 5. 
Result so far: 985.0
The remainder is 201 after subtracting 1100 from 1301.
Append the next digit (6) from the dividend to 201 and continue with: 2016 / 220

Moving on to step 7:
The number 220 fits into 2016 9 times, leaving a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 9859.0
The remainder is 36 after subtracting 1980 from 2016.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 220

Advancing to step 8:
The number 220 fits into 369 1 times, leaving a remainder of 149.
Use 1 as the next digit of our solution. 
Result so far: 98591.0
If we subtract 220 from 369, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 9:
220 can be fit into 1490 6 times, resulting in a remainder of 170.
Use 6 as the next digit of our solution. 
Result so far: 98591.6
If we subtract 1320 from 1490, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 10:
If we divide 1700 by 220, we get 7 and a remainder of 160.
The next digit of our result is 7. 
Result so far: 98591.67
Subtracting 1540 from 1700 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 11:
The number 220 fits into 1600 7 times, leaving a remainder of 60.
The next digit of our result is 7. 
Result so far: 98591.677
If we take 1540 away from 1600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 98591.677, and the remainder is 0.006.
